Gray platelet syndrome: Management of perioperative bleeding in redo cardiac surgery

Gray platelet syndrome (GPS) is a rare (<1/1 000 000) and inherited platelet function disorder characterized by macrothrombocytopenia, α-granule deficiency, and hemorrhages. Bleeding intensity does not correlate with platelet count nor with functional test results. We hereby describe the perioperative bleeding prevention and management of a patient with GPS requiring multiple redo cardiac surgeries.     

Gastric volvulus and giant Bochdalek hernia in an adult patient that were safely repaired by endoscopic reduction and elective laparoscopic surgery

A Bochdalek hernia (BH) is a congenital abnormality with incomplete closure of the diaphragm. It is usually manifested in infants but rarely in adults. Here, we report an adult patient with gastric volvulus and giant BH that were safely repaired by endoscopic reduction and elective laparoscopic surgery, respectively. A 79-year-old woman presented with left upper abdominal pain but no history of trauma. CT revealed a giant BH with gastric volvulus. After emergency endoscopic reduction of the volvulus, elective laparoscopic repair of the BH was performed. The 8 × 8-cm defect was repaired with interrupted nonabsorbable sutures and a mesh. The patient's postoperative course was uneventful, and no complications or recurrence were observed in the 6 months that followed.     

Advance in Functional Restoration of Injured Nerve with Low Level Laser and its Utilization in the Dental and Maxillofacial Region

The inferior alveolar nerve and facial nerve are the two most important nerves in the dental and maxillofacial region. The injury to them is one of the major postoperative complications after alveolar surgery and orthognathic surgery. However, recovering the nerve function after injury takes a long time and the recovery effect tends to be unsatisfactory. In recent years, an intensively investigated technique, low level laser which has been applying in assisting the recovery of nerve function, has been gradually proved to be effective in clinically treating postoperative nerve injury. In this article we review in terms of the mechanisms involved in low level laser-assisted functional restoration of nerve injury and its clinical application in the recovery of nerve function in the dental and maxillofacial area as well.

从TaTME发展看直肠癌微创外科治疗进步

随着科学技术的进步和对疾病本身认识的深入，直肠癌的外科治疗从局部切除到全直肠系膜切除（TME），从开放手术到腹腔镜手术，再从腹腔镜手术到机器人手术，目前已经进入微创时代。在此时代背景下，经肛门全直肠系膜切除（TaTME） 应运而生。正如TME的提出者Heald所言：“TaTME是近30年直肠癌外科治疗技术的集大成者”，其发展的每一个阶段都有很强的代表性，已成为直肠癌微创外科治疗技术进步发展的一个缩影。

??Objective    To investigate the characteristics of indirect injury of periodontal membrane caused by maxillofacial impact injury. Methods    The study was carried out at the laboratory of oral and maxillofacial trauma in Fourth Military Medical University??from November 2013 to January 2014. Totally 18 dogs were divided equally into six groups with random allocation??the right mandible of each dog was impacted by a cylindroid iron cap whose weight was 0.26kg??but teeth were not injured directly??the animals were killed 6 h??24 h??3 d??7 d??2 wk and 4 wk later??respectively??the histopathologic manifestations of periodontal membrane of the fourth premolar of right mandible??the second premolar of right mandible and the second premolar of left mandible were observed. Results    The injury of periodontal membrane of the fourth premolar of right mandible was relatively obvious??but the pathologic changes were reversible??periodontal membrane of the second premolar of right mandible was injured slightly??yet no obvious histopathologic change could be observed in periodontal membrane of the second premolar of left mandible. Conclusion    Maxillofacial impact injury can cause indirect injuries of periodontal membrane of adjacent teeth??but the pathologic changes are reversible??traumatic severity decreases as the distance of the tooth to the wound area increases.
